A Single Car Emits Two Hundred Pounds of Carbon per Week

With 240 Million Cars in the U.S. and Canada, that’s 1 billion extra tons of carbon in the atmosphere EVERY year. If we’re going to mitigate catastrophic climate change, we have to do better, and Carbon Codex can help.

How It Works

Transportation is the largest single source of greenhouse emissions. In order to mitigate the effects of climate change, we must reduce the amount of carbon we generate from inefficient modes of transit.

CODEX tackles this problem by helping you build better habits. Our app quantifies the carbon saved whenever you bike, walk, or take mass transportation.

It then generates carbon offsets from this algorithmically-verified data, tokenizes the data, and stores it on a secure blockchain.

This provides you with clear feedback, providing a way to offset your emissions, and allows you to generate and
sell your carbon offsets from verified low-carbon transportation choices
